Import Tips
• Pair with FDA Drug Master File or DMF reference for pharma import; common error is missing INN documentation shifting to general chemical
• Declare <1% impurity profile per USP standards; CBP tests for isomers that could reclassify under note (b) mixtures
• Use refrigerated transport (2-8°C) with stabilizers only if per note (f); excess additives trigger 3824 mixture classification
